is, those welts which are characterized by means in the welt itselfto-conceal, when in" operative position, the naits, tacks or otherattaching means employed to secure the welt in place on the vehicle topor body to be trimmed.

It is an object of the present invention to provide a simple andinexpensive blind nail welt embodying a base formed of any suitablematerial anda plurality of parallel, longitudinal fillers contained inbeads superposed upon the base and formed of a portion ofthe materialwhich forms the base, one of which v fillersis of novel formation andboth of which cooperate when applied in place on a support to be trimmedto provide an eflicient, attractive and durable blind nail welt. I a A-further object is to provide a-double bead blind nail welt having in onebead a filler of a novel shape and disposition in the welt structureadapted to overlie in part and assist in holding down in place thefiller con tained in the other bead of the welt.

Another object is to provide a welt which is an improvement overthe-finishing welt disclosed in United States Letters Patent No.1,719,729, issued to me on J uly- 2, 1929.

Other and further objects will sufliciently 46 appear as the descriptionproceeds.

In 1 the accompanying drawings, which form part of this applicationforLetters Patent and wherein corresponding reference charactersdesignate the same parts in the several views:

Figure 1 is a perspectiveview, in section at one end, of apportion ofwelt embodying the present invention Fig. 2 is a cross sectional view ofthe im- I 5t) proved welt showing the same in process of being appliedto an article of manufacture, as for example an automobile seat;

Fig. 3 is a cross sectional view showing the welt innfinished appliedposition and illustrating to advantage the coaction of the two.beadportions to conceal the fastening tacks;

and

Fig; & is a perspective view, in section at one end showing the noveltype of core-0r filler used in this invention.

.Referring to the drawings, the reference numeral 1 thereon indicates acovering of suitable flexible fabric, such for example as leather,imitationleather or other textile ma- 1 terial commonly employed in weltstructures. This covering material is looped over upon itself along itslongitudinal ed es to provide oppositely disposed marginal Eeads, eachof which encases a filler or core, designated respectively 2 and 3, andalong the portion of the fabric substantially midway between. theloopsand on the side thereof which contacts with the beads is disposed aninner base strip 4, preferably of the same kind of maerial as thefabric 1. While I have shown this strip 4- as a piece separate from thebead encasing portion of the fabric 1, it is to be understood that itmay be made integral therewith without departing from the spirit of mypresent invention.

In any event, a multi-ply welt base is provided, between the plies ofwhich is received one edge of .a pliable wire weft fabric insert 5, theo posite edge of which is inserted between tiie filler 2 and the bead ofhe encasing fabric 1 which encases said filler. The insert 5, filler 2and the adjacent portion of the fabric 1 are preferably cementedtogether, and, if desired, a line of'stitching 6 may be employed tosecure the two contacting fabrics together underneath the filler 2.

As more particularly explained in my prior patent above identified, thewire weft insert 5 thus provides a pliable hin ing member to permit thefiller 2 to be lifte from the position shown in Fig. 1 to that of Fig. 2and to hold the filler 2 in the latter position while fastening tacks orthe like 7 are passed through the base portion and into the support towhich the welt is to be applied. When 1 therefrom at a slight angle tooverhang a part I the filler 2 at all. times except when a deliber- 'thefiller 2 is pressed down upon the base to conceal the tacks 7, as shownin Fig. 3, "the 3 position .wire' fabric insert 5 tends to retain thebead and its filler in this pressed down POSltlOIl.

It is an object of my'present invention to provide a filler 3 which byits form and disfree edge of the filler 2 when the welt is in singlecylindrical segment, wh le the opposite its finished, applied position,for the purpose of aiding in retaining the filler 2 in its pressed downposition and of effectually preventing gapping or'lifting of the filler1 from the base portion, especially in those sections of the appliedwelt which must be disposed about curves. To this end I provide -afiller 3 of any suitable material, such for example as moulded orextruded rubber, of a form which,

as shown to advantage in Fig.4, may be described as kidney-shaped incross section. In

other words, the filler 3 may be re arded as a single unitary core whichis in e ect a pair of cores, each of elliptical cross section, coalescedor merged together with their major axes forming an obtuse angle. Onesurface of this filler 3 is preferably in the form of a surface isformed of apair of smaller cylindrical segments which meet to produce asub- 'stantially central longitudinal depression or groove 8,asbestshown in Fig. 4.

The filler 3 may or may not be secured in itsbeadby means of cement; andthe filler and its enclosing head .are attached to the base portion ofthe welt by a line of stitches 9, whichpass in the depression or groove8 through the bead, filler and .welt base.

It will be apparentthat'by the construction just described the filler 3is disposed in its head with its outer edge held against the shown inthe embodiment of the invention base of the welt, and with its-inneredge raised of the base. Into the recess formed between this overhangingpart of the filler ,3 and the welt base is received the free edge of thefiller 2, and the, fillers are so proportioned that when disposedintot-he final finished position showninFig. 3 the overhanging portionof the bead which encases the filler 3 will be urged downward snuglyagainst the head in the welt structure will overlie the base along aline intermediate the edgesof its bead and which is ada ted to receiveunder its inner edge the free go of a coacting other head of the welt.Other modifications may be made in the embodiment which I have chosen toexemplify the present'invention, but it is to be understood that allsuch modicharacteristics of a filler secured to the welt fications areto be considered within the scope and purview ofthe appended claims inso far as theyembody the principle of the invention.

Havin thus described my invention, what 7 I claim nddesire to secure byLetters Patent is:

' 1. A blind nail finishing welt comprising a covering fabric foldedupon itself to form,

a nail receiving base portion and forming on opposite marginal edgesthereof a pair of beads, one of the beads being movable to close downupon and overlie the base portion.

bead which is adapted to overlie the first bead is curved upwardly fromthe base ortion to providea recess for receiving the rst head.

4. A welt as claimed in claim 1 inwhich the filler in the second bead isprovided on its upper surface with alongitudinal weaken ing groovethrough which the stitching passes and on its lower surface with an nwardly curving portion to provide a recess etweensaid portion and thebase adapted to receive the first bead. a

'It is to be understood hat while I have illustrated by the drawingsand-described herein a filler 2 of half round formation, this filler maybe provided in any suitable shape. Furthermore the filler 3 need not beof the specific shape which I have herein shown and described, as longas it exhibits the essential
